A Guide to a Science-Inspired Reborn HE

My next book is Let Me Be a Carefree Slacker, so please add it to your to-read list! Blurb for this book: As a native of the Detective Conan world, Tsukimiyama Haruka thought that when he became bound to the System, his life would have a happy ending, just like a novel. Instead, after struggling his way through one ordeal after another, he wound up with a tragic bad ending. Tsukimiyama Haruka: ...I'm tired. The World's Will: How about trying a second run? Tsukimiyama Haruka: ? The World's Will sent him back seventeen years. After thinking it over, he decided to make a few changes. For example, he would adopt himself. System: ? He dutifully raised the child and sent him off to the police academy. Just as he was planning to infiltrate the Organization again and dilute its alcohol supply, the child he had raised told him, "You don't have to go. I've already gone undercover." Tsukimiyama Haruka: ? As it turned out, the child he had raised not only went undercover, but also brought home a Public Security agent whose cover had been blown and who had nearly been killed. Tsukimiyama Haruka: ...What a filial son. I'm dying of pride. If you got to live your life a second time, what would you do? Tsukimiyama Haruka: Thanks for asking. First, I'll kick a few people off the casualty list, so one certain blond idiot won't have to visit five graves all by himself on Qingming Festival. He can barely get through them all as it is. 1. Updates are generally daily, around 10 p.m. If anything comes up, I'll post a notice. 2. The male lead adopts a child from the start. Yep, it's himself (the same person, from another timeline), but there probably won't be much child-rearing in the story. 3. The male lead is firmly on the good guys' side, but he isn't exactly a good person, nor is he perfect. Please don't read if that bothers you. 4. I'm a pretty ordinary author who likes familiar tropes and has very few dealbreakers (so I'm not sure what to warn about). If anything bothers you, please quietly move on. Maybe we'll meet again another time! 5. No pairings other than the canon couple, but Shuichi and Akemi won't be a couple here. 6. My writing and IQ are limited, so characters may be out of character. Please don't insult them. Advance notice: Let Me Be a Carefree Slacker After quitting the police force, Kashiwabara Saku decided on a new goal: to become a wealthy slacker. But a few months later, a manga app mysteriously appeared on his phone. It contained just one ongoing series, about five hot-blooded young men, all but one of whom eventually died. Kashiwabara Saku: ...That's rough. At first, he thought it was just a manga. He stayed up all night reading it, then slept in the next morning and didn't hear the police order people to evacuate. He failed to get out in time and was blown sky-high by a bomb. Only then did Kashiwabara Saku realize that the apartment building blown up in the manga was his home, and that the events in the manga would all play out in real life. Kashiwabara Saku, who had been happily lounging around: You blew up my home? You're done for. The app sent him back to the day before he read the manga. The moment Kashiwabara Saku opened his eyes, he got out of bed without a word and opened the door, coming face-to-face with the criminal planting a bomb. Kashiwabara Saku raised a hand and greeted him expressionlessly. "Hello there." Hagiwara rushed to the apartment after receiving the emergency call. As soon as he went inside, he saw a helpful citizen, presumably the caller, standing on top of a suspect who had apparently been planting a bomb, making the suspect bang his head on the floor three times. The man with moss-green eyes still seemed dissatisfied. He urged the criminal, "What were those words I just taught you? Say them." The bomber burst into tears. "I planted the bomb! I'm terribly sorry for causing you trouble. I deserve to die... Please, just arrest me already!!" The last part sounded completely sincere. Hagiwara: "..." Kashiwabara Saku: "People rejoice in being alive, while I say that death is insignificant and truth reigns supreme." Please see the advance notice for content warnings.
